Three problems related to radiator have been reported for the 2004 Lexus RX330. The most recently reported issues are listed below.
Have had to replace radiator 3 times & will need a 4th at this time, since 2015, was bought used in 2014. !st replacement 2015 2nd) 2016, 3rd) 2017, and now needs again. Many websites state many different problems related to my vehicle, as well as others of a new year ie; 2005, 2006. Lexus claims VIN is the only source to verify if needs fixing stated to me, yet a websource clublexus. Com/forum shows a statement by Lexus stating the issue is not by VIN alone but by make model & year. A local radiator shop in western stated to me via phone that Lexus dealership service for a while in past had ordered many, many radiators because as it was stated some kind of electrical issue was causing the antifreeze to become acidic and destroying radiator from within. This is another not well known issue with this model that seems to have not been made public that I can find. My radiator mechanic that replaced mine 2 of the 3 times stated that the radiator was leaking could not find any other issues in 2015, & 2017. This implies that the issue stated from previous stated website isn't even the issue that I'm experiencing. My closest Lexus dealership is aware of the acidic problem based on statement given to me by the local radiator ship rep that I talked to.
2004 Lexus Rx330. Consumer writes in regards to warranty coverage enhancement. The consumer stated a radiator leak was discovered during an oil change. The consumer stated the indicator light, never illuminated to alert her there was a problem.
I bought my Lexus in 2007. It is a 2004 RX Lexus 330 it had 31,000 miles when bought. Since I had the car my radiator was broken and the Lexus dealership repaired it under warranty. Before this I remember stopping to the dealership because felt the car was stalling and was told that nothing wrong its just I have to be consistent the way I drive with speed. Now in 2010 I'm experiencing the same problem with the car stalling or lagging with the rpm and a little noise coming from the transmission. I really think they should recall this or do something about it because I read alot of reviews that this is happening and the car doesnt even have that many miles. I spent alot of money on this car and they should take this problems in consideration really.
